Negrin wanted Osorno to let him inside the car to "resolve a problem and finally respect him," according to the police report. When Osorno refused to open the passenger door, Negrin allegedly came around the vehicle and took out his police baton.

He then allegedly said in Spanish: "Get on your knees or I will kill you and you better apologize," two other TSA agents told police.

"I'm going to blow your head off," one of the officers also allegedly heard Negrin say.

With the police baton, Negrin then started to hit Osorno on his arms and back. Osorno told police he "was in fear" and apologized. Negrin the left the parking lot in his own car.

Osorno was treated for his injuries by the fire department in the lot. He suffered bruises and cuts on his back and arms. Negrin was arrested the next day at his post at the TSA checkpoint.

Negrin was charged with aggravated battery and released Wednesday night on $7,500 bond.

Miami TSA Officer Allegedly Attacks Co-Worker

TSA spokesman Greg Soule said the agency has a zero tolerance policy for workplace violence.

"Per our normal procedures, TSA is moving quickly to act on the security officer charged with assault," Soule said. "At the same time, we are investigating to determine whether other officers may have violated procedures during a training session with coworkers and committed professional misconduct."

He added that the training was internal and at no time was anyone from the traveling public involved.

"Inappropriate comments in the work place are not acceptable and will be dealt with swiftly," Soule said. "This is an isolated incident that we take very seriously."

The full-body scanners were slowly phased into airport security at several locations across the country in 2008, but their use expanded this year after the failed Christmas day bombing attempt of a Delta flight from Amsterdam.
